Is it feasible to send text messages ?

[seulater]

I am wondering if there is an alarm condition can we send out a text message to a phone ?

I send phone text msgs via email all the time, so it's just as feasible as sending an email.

If you use a GSM modem then you can send SMS messages easily without the need to be connected to the internet. All you need is a serial RS232 port.

If you use text mode your code is easy to develop but you are limited to about 140 or so characters. With PDU mode you get the full 160 characters but this will require more work on the development side.

I have used this: http://www.sparkfun.com/commerce/produc ... ts_id=7917 gprs/gps modem to send email messages with current location before in testing. It had the functionality to send sms as well, but I never used that, email sufficed for the testing I as doing.
